Hattori Tadasaburō (服部唯三郎) was a Japanese cloisonné artist from Nagoya. Along with Kawade Shibatarō, Tadasaburō developed the moriage or "piling up" technique which places layers of enamel upon each other to create a three-dimensional effect. Many of his works are held in collections such as the Victoria & Albert Museum and the Khalili Collection of Japanese Art.
